Common File Extension Variations: H, h

Author: Various

The H file extension is used to signify header files used by C++ and Java source code files. H header files store details about the source code file's contents and provides details about its use to other files and programs. H header files can contain variables, functions and constants that are referenced by other files during programming. H header files can be written once and then referenced by multiple files and applications, so they are used to store general data, rather than write specific file data for each reference. H header files are written in source code and automatically generated with the compiler. H header files can be edited with the appropriate software.
